Monitoring system capable of monitoring floating slab track displacement

Abstract

The invention discloses a monitoring system capable of monitoring floating slab track displacement. The system comprises a base, a controller, a power supply, a laser range finder and an alarm; an angle sensor is arranged in the base; the output end of the controller is electrically connected with the alarm; the signal end of the angle sensor and the signal end of the laser range finder are electrically connected with the input end of the controller; position reflecting plates are installed at the two diagonal ends of the base correspondingly; and the positive and negative pole ends of the controller, the angle sensor, the laser range finder and the alarm are electrically connected with the positive and negative pole ends of the power supply. According to the system of the invention, floating slab displacement change can be remotely monitored in real time, a large amount of manual measurement time is saved, the error of manual measurement is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of track engineering, in particular to a monitoring system capable of monitoring the track displacement of a floating slab. Background technique [0002] The measurement of track displacement can be carried out on-site by means of LVDT displacement sensor, eddy current displacement sensor, strain combined equal intensity beam, and laser displacement sensor. Among them, LVDT displacement sensor and strain equal intensity beam are contact measurement, eddy current and laser displacement sensor It is a non-contact measurement; the eddy current displacement sensor can only be used to measure the dynamic displacement of metal objects, and has relevant requirements for the thickness of the measured object. The eddy current effect is mainly concentrated on the surface of the measured body. If the residual magnetic effect is formed during the processing, and the uneven quenching, uneven hardness, and uneven crystal ...

Problems solved by technology

The displacement of the position under the floating slab track measured by the traditional test method actually includes the displacement of the floating slab, the displacement of the bending deformation of the floating slab and the displacement of the tunnel wall, and is not the real displacement of the position under the floating slab track; Patent No. CN203054222U discloses a laser rangefinder with an angle measurement function, but does not have a parameter processing function; and due to manual on-site detection, the track displacement data cannot be transmitted in real time, and automatic monitoring cannot be achieved
